A process has been developed to produce a crossed-lamellar-type microstructure in mullite combining tape casting, oriented lamination, and templated grain growth. Ceramic laminates were produced with aligned rod-like grains with the alignment direction varying from layer-to-layer with abrupt interfaces between layers. Other designed microstructures are also possible using this process.
